Performance Portability, Reliability, Usability, and Maintainability of PT. ASDP Indonesia Ferry’s E- Procurement Website Based on ISO/IEC 25010 Standards)

Website quality influences customer satisfaction, building a positive reputation, time, cost, and process efficiency. The importance of a website for a company’s professionalism means that website quality assurance is crucial. A comprehensive software quality assurance standard is ISO/IEC 25010. This international standard serves as the basis for measuring the quality of web-based software. The software product quality model includes eight characteristics: functional suitability, performance efficiency, compatibility, security, usability, reliability, portability, and maintainability. The E-Procurement website is the operational medium for PT. ASDP Indonesia Ferry’s digital business. The company’s efforts to ensure website quality have been measured using the ISO/IEC 25010 standard, which is limited to four characteristics: functional suitability, performance efficiency, compatibility, and security. This study proposes measuring website performance by examining four other characteristics: usability, reliability, portability, and maintainability. Performance measurement was carried out using the Mean Opinion Score (MOS) method and the WAPT test tool. The results showed that the usability characteristic reached 83%, meaning the system is simple enough to be used and understood by users. The website’s reliability proved stable and capable of handling access loads without failure, according to WAPT testing. In terms of maintainability, the use of the component-based Angular framework simplifies system development and maintenance. Portability testing showed the website experienced no significant issues across browsers and operating systems. These four characteristics demonstrate that the E-Procurement website is easy to use, highly reliable, easy to maintain, and compatible with various platforms.
